Alfred Nobel Died in 1896 and Left His Fortune to Fund the Nobel Prizes

Wu Zetian (624–705 AD) is the only woman in Chinese history to assume the title of Empress Regnant, ruling China in her own name from 690 to 705. She rose from court concubine to empress consort under Emperor Taizong, then effectively ruled through her husband Emperor Gaozong, and finally seized power outright. Under her reign, Tang China expanded its territory, and she reformed the civil service examination to favor talent over aristocratic birth, recruiting brilliant officials regardless of background.

In 1949, French philosopher Simone de Beauvoir published 'The Second Sex' (Le Deuxième Sexe), a landmark work of feminist philosophy that argued women are not born inferior but are made so by society. Her famous opening phrase — 'One is not born, but rather becomes, a woman' — challenged the idea that femininity is natural or inevitable. The book sold 22,000 copies in its first week, was banned by the Vatican, and became a foundational text of second-wave feminism worldwide.

Katherine Johnson, an African American mathematician at NASA, computed the orbital mechanics for multiple critical missions including the first American crewed spaceflight (Alan Shepard, 1961), John Glenn's orbital mission (1962), and the Apollo 11 Moon landing (1969). Glenn famously refused to fly unless Johnson personally verified the computer's trajectory calculations. She worked at NASA for 33 years and was awarded the Presidential Medal of Freedom in 2015. Her story was told in the film Hidden Figures (2016).

Hedy Lamarr, one of Hollywood's biggest stars in the 1930s–40s, was also a self-taught inventor. During World War II, she co-invented (with composer George Antheil) a radio guidance system for torpedoes using frequency-hopping spread spectrum — a technique that changes radio frequencies rapidly to avoid jamming. The US Navy initially ignored the patent. Decades later, this technology became the foundation for Wi-Fi, GPS, and Bluetooth. Lamarr received the Electronic Frontier Foundation Pioneer Award in 1997.
